课程名称：电力系统中的所有电气变压器 课程概述：本课程探讨了电力系统中最重要组件——电气变压器的分析、设计和实践方面。课程提供了重要且独特的解释，辅以实际图片、应用和现实中的例子。学员和学生将能够在电力分配和传输领域的劳动力市场中具备竞争力。您将掌握变压器的所有技术细节及在变压器设计领域进行技术计算的技能。变压器是将一种电压水平转换为另一种电压水平的设备，既可以升压也可以降压。变压器的主要特性是将供给初级绕组的总功率无重大损耗地传递到次级绕组。这可以增加或减少交流电路中的电容、电感或电阻值，换句话说，它作为一种阻抗变化单元。此外，变压器可以阻止直流电流在两个电路间传递，并可以电气隔离两个电路。为了实现上述任务，有多种类型的变压器，包括： 1. 配电变压器 - 提供电力分配系统中的最终电压，基本上是一个降压变压器。 2. 主变压器 - 通过长距离线路维护电网的盈利能力和可靠性。 3. 熔炉变压器 - 用于升压和降压，超出标准商业电力额定值。 通过本课程，学员将深入了解电气变压器的工作原理和应用，提升自身在电力行业中的专业能力。
This course deals with the analytical, designing and practical aspects of the most important components of the electrical power systems "Electric Transformers."I present important and unique explanation supported by practical pictures, applications and examples from reality. Trainees and students will be able to compete in the labor market in the field of distributing and tranferring electricity at many companies.You will be to gain the skills and understand all kinds of technical details in transformers and how you can do technical calculations in the field of the transformer design.Transformers are the devices which convert one voltage level to another voltage level. it can be either step up or step down. The main characteristic of the transformer is it forwards the total power which is supplied to the primary to secondary without a considerable amount of loss. This can increase or decrease the value of capacitance, an inductance or resistance in the AC circuit. In other words, this work as an impedance changing unit. Also, this can prevent passing DC current from one circuit to another and it can electrically isolate two circuits. there are various types of transformers to achieve the above tasks.Distribution TransformersPower TransformersElectrical TransformersFurnance TransformersDistribution Transformers - provides final voltage to the transformation in the power distribution system. Basically, it is a step-down transformer.Power Transformer - maintain the grid profitability and reliability through a long distance of the line.Furnance Transformer - is used to step up and step down voltage other than standard commercial power ratings.
